Company email (March 2014):
[Clarification regarding Red Knot wines] "In the past we had used egg white (a very ancient and traditional fining agent) only occasionally to aid in the clarification of the Red Knot wine as this product is tightly filtered at bottling. With the introduction of a high tech Cross-flow filter over 4 years ago egg white was no longer required to be used... With our computer recording systems even if 1 litre of older egg fined wine carried over to a younger blend the egg warning was applied."
[Barnivore note] Check older vintages of Red Knot for egg warning. The newer vintages (2009 and later, to play it safe) should be vegan-friendly. Just check the label.
